My motorhome, 2015 Fiat Ducato chassis, has standard orange filament bulbs on the front and side indicators. I was wondering if anyone has replaced these with the LED equivalent? I have read some reports that these replacements can make the electronics think the bulb has blown and trigger a warning (due to their lower power drain) Any of you Tech Guys had any experience with these?

Knowing how Fiat electronics are definitely iffy, I would stay clear.
The main problem is that if the dashboard warning lamp is showing a "fault" at MOT time, the vehicle will fail despite a visual check that bulbs seen to be working.
If the bulbs are easy to change, you can always give it try.
My son changed the bulbs in his VW, all was well for a time, but problems started with ecu showing a fault when the battery became tired which was ok to start, rather than O K !

As above, I'd stay clear of led indicators, whether in a Fiat or otherwise for the very reasons you give 
Though ..... If you want to change the bulbs to remove the yellow 'fried egg' look, then there are chromed indicator bulbs available Chrome bulbs just be careful as some vehicles require offset pins and other don't
